Pure Danny/Jamie moment – I'm still new to these scenes but I hope you like it.

It was past midnight when Jamie woke up again. It took him a few seconds to remember where he was and why he was here – about the same time it took Danny to stop his restless pacing the room and sit down beside him.
"Hey, kid."
"Hey." Whatever the doctors had given him, it hadn't helped. Danny cringed at the raw voice.
"You sound bad."
"I feel bad." And if he was so ready to admit that, it really was badly bad. One day had bent down a police officer, strong and proud and determined not to show any weakness – especially not towards his family and especially there not towards his big brother – to the little boy he once had been. Half a life ago when it had been four of them, a sworn if often quarreling team. Danny sighed. It were days like this when he couldn't help wondering how life would be if Joe was still with them. And their mother. Would Jamie still be a cop? Or would he be a lawyer, married to Sydney, a father probably? What kind of life would he lead if those two were still with them?

It had never occurred to Danny how much those deaths had actually altered in his little brother's life. He was the youngest; his path had been the least laid out when he had lost two of his greatest supporters and counselors. Mary at least had told him – often enough – what she wanted for her last child, and more even what she definitely did not want. Jamie had fulfilled her wish when he had started at the university, and Danny remembered well the mixture of excitement and remorse when they had driven him to Harvard.
Then Mary had died, near the end of Jamie's first year. She had never seen her son graduating, she would never see it – it still was a secret between Jamie and Joe what they had talked about in the night of the funeral, but from the little Danny had managed to get out of Joe they had talked about the new situation concerning Jamie's choice of job then. Without his mother urging him to stand away from family business, why shouldn't he just do it? Why had he decided to stay at Harvard and continue the way his mother had so wished him to go?
And then Joe got killed and everything changed anew. Danny and Erin already had families of their own when they lost their mother and brother, they had jobs and a life and reasons to work for – taxes to pay, at least.
Jamie had still been a student, and though the whole world was grey with grief, it was open for him. He had chosen to return and follow Joe's footsteps, and he was doing a good job so far, but still – it had cost him already much more than it had Danny in all his years.
Sydney gone. Maura dead. A punctured lung that would steal away ten months of his life.

"Are the others okay?" The weak voice pulled Danny back into reality. Trying to steady his expression, he quickly nodded. "Yes, they are. They're all here, waiting down in the hall. I guess grandpa's asleep by now, he and Nicki kept on fighting about school for hours…" he chuckled forcefully and quickly stopped. The echo in the room sounded even more wrong than the noise had felt in the first place.
Jamie straightened up. "Nicki shouldn't be here, Danny. Jack and Sean neither. I…"
"Okay, all was maybe too much, Linda and the boys have gone home some hours ago" Danny quickly reassured his brother, "and if Erin says Nicki's old enough to decide, then…"
"Erin's here?"
"Yes." Danny smiled at the warmth in his brother's voice. Even if his relationship with Erin wasn't the best now, he loved her with all his heart. And seeing Jamie's face light up at the knowledge that she was here, that the siblings were still there for each other, made him love both of them even more.
And made him realize once again how much he needed them.

"I thought she wanted to be away longer" Jamie murmured in confusion.
"Well, she wanted, but obviously…"
"It's good she's here, though." The relief was hearable in Jamie's voice, "Nicki needs her." He took what deep a breath he could take, and Danny felt his stomach twist at the sound.
"What about Jack?"
"He's an asshole" Danny blurted out. Jamie's face changed to a grimace that probably should be a smile. "I see. Is Erin okay?"
"She'll be once you are out of here, kid."

Minutes passed by in silence. Danny almost thought Jamie had fallen asleep again when he said: "I think I was a bad babysitter yesterday."
"You what?"
"For Nicki" Jamie explained tiredly, "I didn't listen to her at all" he ignored Danny's unbelieving look, "I just talked about how great my date had been. I told her about Maura."
Danny nodded. That was where it was heading to. "She had a great evening, too, Jamie. Never forget that."

"I dreamt about her, Danny" the younger one murmured, as if he hadn't heard. "I dreamt about mom and Joe and how they died and then I saw Nicki and just hoped she would be okay, and the next thing I saw was Maura and we fought and then I threw a plate at her face and she died." He started sobbing, and Danny gently took his hand.
"You did nothing wrong, Jamie. Not even with Melissa Samuels. The autopsy's ready, it was brain tumor killing her, not you. Probably that was what drove her that crazy in the first place."

But Jamie still wasn't listening, caught in the one nightmare he wouldn't wake up from anymore. "I dreamt about her death, Danny. I saw it all and I couldn't help her, I was doing it and I couldn't stop myself and now she's dead and I still can't stop it!"
"I'm so sorry, Jamie." Danny's heart broke as he saw his little brother suffer like that, but what comfort could he give him? The only thing he could do now was be there and pray for sleep to quickly come and let Jamie forget for another hours. Till he was strong enough to start getting over it.

Eventually the sobs ebbed down, leaving the room in silence, only to be broken by rasped breathing and the sound of tears falling down Danny's cheeks.
